Seismotectonic maps in the vicinity of the lower Wabash Valley, Illinois, Indiana, and Kentucky - Digital Spatial Database: Gravity and aeromagnetic surveying and modeling lines

Lines in this cover show where gravity oe aeromagnetic data have been modelled to constrain subsurface structure. Gravity and magnetic signatures result from deep structure, such as might be at hypocentral depths of earthquakes. We show only the lines for
